Charles H. Spurgeon on Psalms 91:4

He shall cover thee with his feathers, etc. This is the promise of the present life. For the promise of the life to come, who can explain? If the expectation of the just be gladness, and such gladness, that no object of desire in the world is worthy to be compared with it, what will the thing itself be which is expected? No eye, apart from Thee, O God, hath seen what Thou hast prepared for them that love Thee. Under these wings, therefore, four blessings are conferred upon us. For under these we are concealed:under these we are protected from the attack of the hawks and kites, which are the powers of the air: under these a salubrious shade refreshes us, and wards off the overpowering heat of the sun; under these, also we are nourished and cherished. Bernard.
